ntdll: Fill EnabledFeatures before return.
Followup to 03039ab2.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=58335
If I observed it right we currently leave init_xstate_features on older computers with EnabledFeatures being zero.
This leads in __wine_syscall_dispatcher to getting the xsave64 getting
called with "$rax = 0x0", therefore e.g. xmm6 gets not saved to the stack.
But later e.g. xmm6 gets restored from stack in __wine_syscall_dispatcher (see __wine_syscall_dispatcher)
